This non-provisional application incorporates by reference the subject matter of Application No. 2004-381178 filed in Japan on Dec. 28, 2004, on which a priority claim is based under 35 U.S.C. §119(a).
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a vehicle door structure for opening and closing a door opening formed in a vehicle and, in particular, to a door structure that has a side impact bar.
2. Description of the Related Art
In an inner panel provided in a door of a vehicle for opening and closing a door opening formed in a vehicle, there is formed an opening which is used to mount various kinds of equipment such as a window regulator into inside the door. This opening, after mounting of the equipment, is closed from the inside of a vehicle room with a sheet member such as a vinyl sheet or is closed with a panel member made of resin (which is hereinafter referred to as a resin panel. Inside the door, in order to enhance the safety of the vehicle against collision from the side surface of the vehicle, there is provided a side impact bar having a square-shaped, U-shaped or round-shaped section, with its two ends respectively fixed to the front and rear ends of the door.
Generally, in order to secure the mounting rigidity of the window regulator, the window regulator is mounted onto the inner panel of the door with its composing parts integrally attached to a bracket made of sheet metal or to a resin panel. JP-A-10-37592 discloses an example of a window regulator formed as a unit product using such sheet-metal-made bracket.
SUMMARY OF THE INVENTIONAlthough the resin panel is itself light in weight, when the equipment such as a window regulator and a speaker is mounted thereon, the whole of the resin panel becomes heavy in weight due to the weight of the equipment mounted thereon. Therefore, two or more operators are necessary when mounting the resin panel and, with the increased weight, the resin panel is also required of rigidity, resulting in the increased weight of the whole of the resin panel, which can lower the efficiency of the panel mounting operation. Also, recently, there has been raised the need for enhancement in the utility of the inside of the vehicle room.
In view of the above, it is an object of the invention to provide a door structure which, while restricting an increase in weight, can provide high operation efficiency when it is assembled to a vehicle and also can enhance the utility of the inside of the vehicle room.
According to the aspect of the invention, when compared with a structure in which a window regulator is positioned so as to face a side impact bar in the vehicle width direction, there can be provided room in space in the inside of the vehicle door in the vehicle width direction and the thus-increased space in the door in the vehicle width direction can be allocated to the vehicle room. Thus, when forming a pocket in the door on the room inside side thereof, the capacity of the pocket can be increased to thereby enhance the utility of the inside of the vehicle room.
BRIEF DESCRIPTION OF DRAWINGSThe present invention will become more fully understood from the detailed description given hereinbelow and accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention and wherein:
Now, description will be given below of an embodiment of a door structure according to the invention with reference to the accompanying drawings. In
The door 4, as shown in
In the inside of the door 4, as shown in
The resin panel 7 is formed so as to have a size which is enough to cover the opening 6. On the side of the resin panel 7 existing on the interior side of the vehicle room, there is mounted a door trim 9 which is used to not only conceal the fastening portion (fastening member 8) of the resin panel 7 with the inner panel 42 but also define a storage pocket 25 between the resin panel 7 and the door trim 9. The resin panel 7 is formed such that the near-to-center portion thereof projects more outwardly in the vehicle width direction than the neighborhood of the portion thereof fixed to the inner panel 42.
The window regulator 5 is used to lift and lower a door glass 10 which can be stored into the inside of the door 4. The window regulator 5 has a drive motor 51, an arm 52 for holding the door glass 10, and a drum 53 for actuating the arm 52. In
The side impact bars 20, 21 are disposed more outwardly of the vehicle in the vehicle width direction than the glass rising and lowering track. On the side impact bars 20, 21, there is disposed a bracket 22 made of sheet metal with the two ends thereof respectively welded and fixed to the two side impact bars. In the present embodiment, on the bracket 22, there are mounted the drive motor 51 and drum 53. The drive motor 51 and drum 53, as shown in
Since the window regulator 5 is arranged in the section width area A of the side impact bars 20, 21 in the vehicle width direction, when compared with a structure in which the window regulator 5 is arranged so as to face the side impact bars 20, 21 in the vehicle width direction, there can be produced room in space in the inside of the door in the vehicle width direction. In other words, when the thus-produced space room of the door 4 in the vehicle width direction is allocated to the inside of the vehicle room, the capacity of the storage pocket 25 formed on the inside of the vehicle room of the door 4 can be increased, thereby being able to enhance the utility of the inside of the vehicle room.
Because the window regulator 5 is mounted on the two side impact bars 20, 21 through the bracket 22 which are connected to the two side impact bars 20, 21 so as to straddle them, the bracket 22 is united with the two side impact bars 20, 21 to increase the support rigidity thereof, thereby being able to enhance the mounting rigidity of the window regulator 5.
Since the near-to-center portion of the resin panel 7 projects more outwardly in the vehicle width direction than the neighborhood of the fixed portion of the resin panel 7 to the inner panel 42, when fixing them together using a fastening member, a clip or the like, the rigidity of the mounting portions of the resin panel 7 and inner panel 42 can be enhanced. Also, because the projecting portion of the resin panel projecting outwardly in the vehicle width direction produces room in space in the vehicle width direction, not only the utility can be enhanced but also the bending rigidity of the resin panel itself can be enhanced. Further, since the window regulator 5 for lifting and lowering the glass 10 of the door 4 is mounted on the side impact bars 20, 21 arranged inside the door 4, the window regulator 5 need not be mounted on the resin panel 7, which eliminates the need to enhance the rigidity of the resin panel 7. This also makes it unnecessary to increase the weight of the resin panel 7, thereby being able to enhance the efficiency of the door assembling operation.
Although, in the present embodiment, the drive motor 51 and drum 52 are mounted on the bracket 22 interposed between the side impact bars 20, 21, the side impact bar structure, as shown in
The invention thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
